The turtle mounts are going to be the racial mounts, because there's normal and Great ("Swift," in other words) versions of them. And there's twelve of them in total--six for us, six for the other side.

Edit: As for the Serpents:

The two Crimson ones are rewards from the expansion's Glory of the Hero and Glory of the Raider achievements. Red is special, but only when it's a flying mount, it seems.

Not sure about the Astral and Thundering ones--one seems Alliance-focused and the other Horde-focused, but that could mean anything from vendor-bought to a 150 mount achievement reward. I suspect we may see at least one of the Heavenly mounts be a boss drop.

Edit 2: Guess not. :P

It became clear that it wasn’t realistic to try to get the audience back to being more hardcore, as it had been in the past. -- Tom Chilton

OMG even now that grind for Netherwing is a pain in the butt. I did the grind on my main toon and think i spent at least 3 days solid flying around grabbing EVERY egg I could find. So glad that the mounts are becoming account wide for MoP so that only my shaman main will need to have them all for all my toons.
